Nonlinear polarization amplifiers in nonzero dispersion shifted fiber |
| 摘要 |
A broadband fiber transmission system includes a transmission line with at least one zero dispersion wavelength lambda<SUB>o </SUB>and transmits an optical signal of lambda. The transmission line includes a distributed Raman amplifier that amplifies the optical signal through Raman gain. One or more pump sources are included and operated at wavelengths lambda<SUB>p </SUB>for generating a pump light to pump the Raman amplifier. lambda is close to lambda<SUB>0 </SUB>and lambda<SUB>0 </SUB>is less than 1540 nm or greater than 1560 nm.
